Coolant Valve The Culprit?

[Tony1965]

I have an issue with my 2019 CX3, the top rad hose gets hot and the bottom hose stays stone cold, rad is not clogged I can squeeze the bottom hose with the rad cap off and the coolant moves. I have good cabin heat. What I have is a coolant smell in the cabin, coolant does not seem to have gone down though. Could the coolant valve be the culprit? No engine codes as of yet.
